INOCULATING. 2 
$$ 
INSECTS. 
rior kinds, surrounded by a number | the imtervening spaces are sown 
uf pots of the common single red, sup- 
ported at different heights, for the 
convenience of reaching the different 
branches to which they have been 
united by inarching. 'The mode of 
grafting shown in fig. 30, p. 233, has 
all the advantage of marching, the 
scion being nourished by the water 
in the same way as it would be by 
its roots, in the case of inarching.

Inpieo is formed from the leaves 
of an Indian plant, called Indigo- 
fera tinctoria, belonging to the order 
Leguminose, and it requires a stove 
in England. The false Indigo, 
Amorpha, also belongs to Legumi- 
nose; and some of the species are 
hardy shrubs or low trees. See 
Amo’RPHA. 
I'nea.— Leguminése.— Beautiful 
plants, nearly allied to the genus 
Mimdsa, with silky,  tassel-like 
flowers. All the species are stove- 
shrubs, and should be grown in a 
mixture of loam and peat. They 
are propagated by cuttings, taken off 
at a joint, and struck in pure sand, 
under a bell-glass, and plunged in a 
hotbed, or in tan, to afford them 
bottom-heat. 
InocuLatinc.—This term, when 
applied to plants, is generally used 
as equivalent to that of Budding, 
which see in p. 135; but it is also 
applied to a mode of creating a 
grassy surface, either for a lawn or 
a pasture-field, by distributing frag- 
ments of turf taken from an estab- 
lished pasture over a newly-formed 
surface. Supposing the surface 
which it is intended to form into a 
lawn, to be levelled, dug, and 
smoothed, rolls of turf are procured 
from any suitable meadow or pas- 
ture, and cut into pieces, and laid 
down on the prepared surface at a 
foot or a foot and a half apart ; and 
22* 
with grass-seeds, and the whole 
firmly rolled. The pieces of turf 
give an immediate character of 
grassy surface, and they are united 
in the course of a season by the 
growth of the intervening grass- 
seeds. It may be asked, why not 
use the grass-seeds alone, and save 
the expense of the turf?) The only 
answer to which is, that the pieces 
of turf being green from the com- 
mencement, anticipate in idea the 
future effect that will be produced, 
and make sure of a grassy surface 
in case the grass-seeds should fail. 
The practice originated in Norfolk, 
and it is sometimes adopted in agri- 
culture as well as in gardening. 
Inoculating lawns with mush- 
room spawn is a practice sometimes 
adopted in gardens in the country, 
and affords at once a source of 
amusement in collecting the mush- 
rooms, and of profit from their use- 
fulness in the kitchen. It may be 
adopted in the case of any lawn, 
whether old or newly-formed. A 
few spawn bricks, as they are called, 
are procured from any person that 
grows mushrooms, or from the seed- 
shops ; and these, being first broken 
into fragments, are inserted in the 
soil, either at a foot or a yard apart, 
according as it is wished to have the 
ground wholly or partially covered 
with mushrooms. The fragments 
are inserted about two inches in 
depth, and the turf is firmly pressed 
over them with the foot. The opera- 
tion occasions no derangement of 
the turf, and it may be performed 
with the corner of a spade ora trowel. 
The time is April or May, and the 
mushrooms will make their appear- 
ance inthe September or October 
following. ‘The turf is not injured, 
and much amusement is sometimes 
produced by the unexpected appear- 
ance of the mushrooms. 
Insects are extremely destructive 
to flower-gardens, particularly those
